I'm hoping that if we wait long enough, 4e will become retro-cool and we'll have a 4e School Revolution (4SR).
Wizards will actually open-source the 4e rules. There will be an explosion of 4SR materials, including stuff like how to create classes / PPs / EDs to allow for maximum customization.
Meanwhile, one of the DDI developers will reveal he kept a copy of the code repo, which Wizards also approves for open sourcing. Hard working 4SR fans clean up the code to make it run on modern frameworks as well as make it much better and more extensible, allowing for the creation of new software tools to go alongside a rewritten character builder and monster builder.
A golden age of 4SR shines its glorious light across the world!
